Do not try to init the fbdev if either num_crtcs or num_connectors is 0. In this case we do not have display so the fbdev init would fail anyways.

Thierry Redding had patches to implement this in a generic fashion in the fbdev emulation (just wait with fbdev init until the first screen shows up). Would be great to polish up that work (I've reviewed the original series already) and land it, instead of driver hacks forever.
